WATER-SUPPLY SYSTEM.

Specification of Letters Patent.

Patented Nov. 2h 191 'll.

To all whom it may concern:

Be it known that I, HUGH W. KrMEs, a citizen of the United States, and residing at Dayton, in the county of Montgomery and State of Ohio, have invented new and useful Improvements in VVater-Supply Systems, of which the following specification is a full disclosure.

This invention in particular relates to automatically controlled water supply sys tems, primarily for domestic Water service wherein the water from a static water sup; ply source is pumped into a compression tank as a shortage supply under pressure converting the static water in the tank to dynamic form at the fixtures or service outlets.

An object of the invention is to combine such pneumatic water supply system with a direct pump pressure service or branch rendering the pumping apparatus and auto matic controlling device of the pneumatic Water supply service available for aux liary purposes and uses to furnish a supply of fresh water direct from the main supply source or well, so that a joint or independent service of either can be had.

Another objectof the invention is to provide a water supply system including a storage tank and connected pumping apparatus for maintaining the tank water supply with means interposed and communicatively connecting with the piping system between the pumping apparatus and tank, providing a branch circuit for a direct pump pressure supply water service and a check for said tank against a drawing counterflow of water, but non-interfering with the operation of the pressure actuated motor controlling devices.

Another object of the invention is to provide a local or house water supply system, comprising a compression tank, service pipes for supplying water from said tank, pumping apparatus for supplying water to said tank and maintaining a service pressure in said tank, pressure influenced devices for automatic control of said pump apparatus and relief devices operating under varying pressure influences for preventing or relieving any excessive system pressure or overload to protect the parts against injury.

Various other features relate to the various parts of the system for automatic andply service, all more fully revealed in the description of the accompanying drawings, illustrating a preferred embodiment of several of the devices and as combined in a system, and as to the system diagrammatically shown, and in such drawings like characters of reference denote correspond ing parts throughout the several views of which Figure 1 is a side elevation of Ir improved automatic pneumatic water supply system, showing a fresh water or direct pressure branch intermediate the pump and' storage tank. Fig. 2 is a central vertical section of a relief valve used in the system. Fig. 3 is a central section of a by-pass fitting and check valve. Fig. t is a similar view to Fig. 3 of a modified form of valve, showing the valve in open position. Fig. 5 is a central vertical section through the pump, illustrative of valve means for admitting air into the pump and system when the pump is in operation.

Referring to Fig. 1 ot the drawings, 1 indicates a pump mounted upon a support 2 and connected to a water supply source by means of the piping 3, and in series including an air chamber fitting 3'. The pump is driven by an electric motor lconnected by a belt 5 with the fly wheel 6 or the pump. The motor is controlled by a switch device operating under the influence of the pressure in the system for starting and stopping the motor. The eh :tric switch mechanism may be of any wellknown type, and detail description of its working parts need not be herein included. The switch mechanism connects with the system piping through a. pipe 7 and the switch is contemplated to operate after the supply and pressure in the storage tank 8 has been reduced to a determined degree for starting the motor and pump, and permitting the same to continue in operation until a predetermined storage supply and pressure is again restored. Any form of pump and automatically controlled power apparatus may be used in the water supply system within the aspect of this invention,

and as such apparatus is well-hown in the art, detail description thereof is not deemed necessary herein. The pump 1 connects with the tanlr 8 through the piping 9 for supplying water to the tankunder the pres sure at the pump and 10 represents thepip-llu ing connecting with the tank 8, as a ser ice supply line leading to the various outlets.

,As the system has primary use as a domestic water supply outfit, the tank is of a capacity to meet the usual water consumption requirements for a given period, without calling 'for a continued operation of the pumping apparatus, and the tank is essenoutlets.

remains in storage for a sufficient period to tial tothe successful operation for maintaming a constant pressure to the service The water in the tank sometimes the storage supply, and supplied under di-' rect pumping pressure, and for the purpose herein termed cold water supply branch.

In pneumatic water systems of this class under automatic control it is desirable for the safety of the system to install a relief valve 11 connected in series with thepipe 4 system 9 leading from the pump to the storage tank. The relief valve 11 is controlled by the influence of the varying pressure in the system, opening to relieve or prevent any excessive system pressure and an escape of the water. supply from'the pump principally due to the continuing operation of the pump by reason of automatic switch or motor controlling devices failing to j promptly respond to an effective or influ encing degree of pressure. I

I A preferred type of relief valve is shown herein as one especially adapted to .the particular use, arranged to quickly respond in its movements to full open or closing, and avoid any sluggish valve operation, which may cause .an excessive degree of pressure in the system, overload or damage to the system apparatus. This preferred type of relief valve is made the subject-matter of a separate application filed of even date herewith, Serial No. 76,325,and to which referonce should be had fora more comprehensive disclosure than contained herein. In the system herein the relief valve preferably is installed intermediate the storage" tank and cold water supply branch.

resh water or contz'nued supply branch.

. In providing a fresh water or continued supply branch in connectiton with a pneumatic water supply system, including the storage tank and providing a supply independent of the storage tank, I provide water check devices in series with a piping between the pumping apparatus and tank, noninterfering to the pressure influence devices, but capable of approximately checking acounterflow or escape of the storage water supply in the tank. A combined bypassing water check fitting 13 placed in series with the system piping between the pump and tank, and in its preferred form of construction comprises a body 14, as a pipe coupling providing a Water check valve intermediate thereof. A web 15 extends interiorly across the chamber of the body to divide the same and is provided with a valve-seat-equipped opening, having aseat ring 16 fitting therein with the axis preferably in a vertical plane to permit the valve to operate by gravity. The body has a hub extension 17 providing an opening into the body and coaxial with the valve opening for receiving the guide plug 18. 19 indicates a valve which may be constructed either as shown in Fig. 3 or in the modified form shown in Fig. 4, the latter being preferable. In the. form shown in Fig. 3 the valve has the guide wings 20 projected from its upper face slidably fitting an orifice in the guide plug 18. The opposite face of the valve has the guide wings 21 projecting therefrom, which guide the opposite side of the valve within the seat ring, the valve closing toward the inlet side and under the influence of the pressure from the tank side, lifting or opening under the pumping pressure when supplying. the tank. In order to equalize the pressure upon both sides of the valve and not interfere with the pressure controlled devices for starting the motor or relief valve, the valve is apertured as at 22, Fig. 3, or

notched as shown at 23, Fig. 4, to provide a restricted passage affording communication between opposite sides of the valve when closed for equalizing, the pressure upon both sides of the valve. Thevalve is operated or controlled under the influence of the prevailing pressure upon either of its sides, for opening or closing, and when the prevailing pressure is on the system or tank side the valve will be closed and approximately prevent the water from 'escaplng in a counter dlrection. a

to service point desired with the delivery capacity of the pump, and provided with suitable valves or cook controlled outlets. The drawing shows the pipe 25 extended upwardly and provided with a cook 26 for sealing the branch when not in use, which is necessaryso as not to interfere with the normal operation of the system. As shown in Fig. 4, the .valve 19 is provided with-a stem 27 slidably fitting the bore of the guide plug 18, which in the upward movement of the valve compresses the air in the-cap. plug 18 to assist in closing the valve.

The upper face of the valve is also pro The body 14 has a hub extension 24 form.

in operation let it be assumed that the a predetermined pressure which will automatically stop the pumping apparatus and permit the valve 19 to seat. Should it however be desirable to have the supply of fresh water, as for drinking purposes, the valve 26 of the fresh water supply branch is opened, which immediately lowers the pressure in, the piping 9 between the check valve 13 and the electric switch mechanism 29 functioning the switch, starts the motor and operates the pump, forces the water through the pipe 25 and service outlet. The pumping apparatus continues in operation duringsuch service I period.

Upon closing the valve 26, the pressure in the system piping or service line is increased which influences the switch devices for throwing the pumping apparatus out of commission, provided there has been no appreciable loss or reduction in the tank pressure, or consumption of the static water supply, and it so such is restored bev tore the pumping apparatus stops.

The fresh water branch enables the user to get an abundant supply of fresh cool Water direct from the well, at will, for either cooking or household purposes, or

for a more continued water consumption, as
